IMPROVEMENT IN SELECTORS FOR HAIR-CLOTH LOOMS.

Specification forming part of Letters Patent No. 152,982, dated July 14, 1874; application tiled December 13, 1873.

To all whom fit may concern:

Be it knowu'that I, WILLIAM H. DREW, of Brooklyn, in the county of Kings and State of New York, have invented an Improvement in Selectors for Hair-Cloth Looms, of which the following is a specification:

A conical tube, having a sma-ll hole at the apex, is employed in selecting' one hair at a time from a bunch of hairssaid hole being of a size that only admits one hair to pass. This selector is pressed upon the ends of the hairs as they are confined in a bunch, or the bunch pressed into the selector, and the hair that passes into the hole projects sufficiently to be grasped by pinchers, and drawn through the hole of the selector, or preferably grasped by a clamp that holds it in the eye of the selector while the pa-rts move across the fabric, and the pinchers or clamps are moved at the proper time to release or drop the hair between the sheds of warp.

This improvement, although primarily adapt1 ed to hair-cloth, may be used in weaving any goods where the weft is in lengths and sufficiently stiff, and I remark that it may bc used at bot-h ends of a shuttle, so as to operate in two directions, or it may be at the end of a picking-stick.

In the drawing, I have represented the single selector at the end ot' a picking-stick.

Figure l is an elevation of the apparatus with the selector in section, and Fig. 2 is a sectional plan in larger size of the selector.

The hairs are, by preference, contained i n a can, a, of water or other liquid to soften them; but a bag kept wet will answer the same purpose. The ends of the bunch of hair lie in the crotcltplate b, that is V-formed at the lower part, and bands c of india-rubber or similar material serve to draw the hairs down in the crotch, andhold them in place, but allow a yielding movement as the selector c is pressed against the ends of the hairs.

In order to seize the hair forceps or pinchers may be used; but I prefer the swinging clamp t', that is operated by an incline or cam, Z, and swings across at the back of the eye. bending the hair and griping it firmly, so that the hair.

is drawn out' from the bunch and across the fabric between the warp threads, and dropped at the proper place by the action of an incline. or cam, u, that moves the clamp t' to liberate thehair.

It will be evident that, in place of the hollow cone being smooth, there may be grooves occupying radial positions to the eye to direct the hairs toward such eye.

I claim as my inventionl. A reciprocating selector having a conical or converging end to direct the ends ofthe hairs, or their equivalents, and an eye to allow the passage of a single hair, in combination with nippers, pinchers, or clamps to seize such hair that passes through the eye, substantially as Set forth. l

A conical selector with an eye at the apex, in combination with a clamp that bends and holds the end of the hair at the back ot IVM. II. DREV.
